Caldwell 33 - Supernova Remnant (NGC 6992 , "Veil Nebula, East" ) C/2020 Q1 (Borisov) - Comet (Attempted Sighting) Hickson 93 - Galaxy Group (NGC 7550 et al) ARP 99 - Spiral & Elliptical Galaxy (NGC 7549 & 7550) UGC 122 - Spiral Galaxy (PGC 889) NGC 772 - Spiral Galaxy (ARP 78 / H112-1) with AT 2020ue (Unconfirmed)     Variable Stars (photometric monitoring) - RX And, BL Lac     Nearby Stars (astrometric monitoring) - None

- Night session (1.5 hours), excluding time spent focusing and testing /calibrating 'Cam1' Autoguiding. - Main aims of the session were the testing new PHD2 messaging routines and acquisition of a selection of deep sky targets, together with some variable star, nearby star and comet targets (if conditions allowed) - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 3°C (min) - CCD Temperature:  -20°C - Notes from 2020-10-08 >>      -
